Understanding rhythmic behavior in infancy: Perspectives for addressing developmental, methodological, and analytical challenges

Neural sensitivity to rhythm emerges prenatally, yet observable movement synchronization to an external beat occurs later and more gradually over development. Integrating findings from developmental psychology, neuroscience, music cognition, and social interaction research, we pr...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Semiclassical tunneling for some 1D Schrödinger operators with complex-valued potentials

We consider the non-selfadjoint, semiclassical Schrödinger operator \mathscr{L}(h) := -h^{2}\partial_{x}^{2}+e^{i\alpha}V , where \alpha \in (-\pi,\pi) and V\colon \R\to \R_{+} is even and vanishes at exactly two (symmetric) non-degenerate minima. We establish a semiclassical tun...

Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐pressure hydrogen tanks. Rotational m...

Dry snow initialization and densification over the Greenland and Antarctic ice sheets in the ORCHIDEE land surface model

Abstract. Accurate modeling of the snowpack over ice sheets is essential for quantifying their surface mass balance contribution and their resulting impact on sea level rise. The snowpack evolution is largely governed by surface climate but also by internal processes such as dens...

A Frank-Wolfe-based primal heuristic for quadratic mixed-integer optimization

Abstract We propose a primal heuristic for quadratic mixed-integer problems. Our method extends the Boscia framework – originally a mixed-integer convex solver leveraging a Frank-Wolfe-based branch-and-bound approach – to address nonconvex quadratic objective functions and constr...

Evaluation of smoke mass concentration within the PBL based on observations of fluorescence lidar with several discreet channels

Abstract. Elevated concentrations of smoke within the planetary boundary layer (PBL) represent a significant health hazard, making its monitoring essential. This study demonstrates that a multi-channel fluorescence lidar can effectively analyze smoke–urban aerosol mixtures and re...

NucGen3D: A synthetic framework for large-scale 3D nuclear segmentation with open-source training data and models

A bstract Robust nuclear segmentation in 3D microscopy images is a critical yet unresolved challenge in quantitative cell biology, hindered by the scarcity and variability of annotated volumetric datasets. Because such data are difficult to obtain, most state-of-the-art approache...

Multi-stage single-cell atlas of a chordate non-embryonic development unveils dedifferentiating bud founder cells

Abstract Colonial tunicates are the only chordates capable of forming fully functional bodies from somatic tissues through non-embryonic development, or budding. In Botryllus schlosseri , budding produces new individuals (zooids) from a portion of the peribranchial epithelium of...

Pattern-Anchored Diagnosis of Oral Epithelial Dysplasia: A Position Paper From COST Action INTERCEPTOR Working Group 2

Abstract Purpose Oral epithelial dysplasia (OED) is the principal histopathological marker for malignant risk stratification in oral potentially malignant disorders (OPMDs). Current World Health Organisation (WHO) three-tier and other binary grading systems are limited by modest...

Joint Inversion of Seismic and Geoelectrical Data Targeting Geological Faults

Near-surface geological faults play a crucial role in subsurface systems because they influence fluid flow and transport and can cause geotechnical failure. Topography can sometimes indicate the presence of fault zones, particularly in active tectonic settings where geomorphic fe...

Oscillatory Traveling Waves During Visual Entrainment in Autistic and Non-Autistic Adults

Neural oscillations and traveling waves play a crucial role in cognition. In scalp electroencephalography (EEG), waves typically travel along the anterior-posterior axis: forward waves (occipital-to-frontal) predominate during sensory stimulation, while backward waves (frontal-to...

Widespread circulation of West Nile and Usutu viruses in sedentary and migratory avifauna: A two-year study (2024–2025) of active surveillance in South of France

Abstract West Nile virus (WNV) and Usutu virus (USUV) are neurotropic Orthoflaviviruses sharing a similar enzootic transmission cycle primarily involving Culex pipiens mosquitoes as vectors and birds as amplifying hosts. First identified in Africa, both viruses established endemi...

Longitudinal evidence for decreasing statistical learning abilities across childhood

Abstract Statistical learning enables us to identify patterns in our environment and predict future events, thereby supporting a range of motor, cognitive, and linguistic skills. Despite its significance, the developmental trajectory of statistical learning has remained unclear d...

A barycenter-based approach for the multi-model ensembling of subseasonal forecasts

Abstract. Ensemble forecasts and their combination are examined from the perspective of probability spaces. By treating ensemble forecasts as discrete probability distributions, multi-model ensemble (MME) forecasts are reformulated as barycenters of these distributions. We consid...

Reproducible human reward imaging phenotypes exhibit differential sensitivity to dopamine D2 receptor antagonism

Abstract Human reward processing varies along cue-centric and outcome-centric axes, but a reproducible mechanistic account of individual variation in incentive salience attribution has been lacking. Using fMRI across five cohorts (N-total=1,251; N1=890; N2=245; N3=34; N4=48; N5=3...

Matrix‐Activated Aptamer Sensors for Human Serum Analysis

ABSTRACT Owing to their ease of operation, solution‐phase fluorescent sensors hold a crucial position among aptamer‐based detection tools. However, their performance is regularly compromised when exposed to increasing levels of blood fluids, such as human serum, which limits thei...

Movement of European freshwater mussels under simulated dewatering conditions

Freshwater ecosystems are exposed to altered hydrological regimes due to climate change and poor water management, resulting in frequent and intense dewatering events. Freshwater mussels (Unionida) are particularly vulnerable to rapid water-level declines. Dewatering can lead to...

The algebraic structures of social organizations: the operad of cooperative games

The main goal of this paper is to settle a conceptual framework for cooperative game theory in which the notion of composition/aggregation of games is the defining structure. This is done via the mathematical theory of algebraic operads: we start by endowing the collection of all...

Learning behaviour is consistent across time and tasks in Formica fusca ants

Abstract Research on interindividual behavioural and cognitive variability has gained momentum over the last few decades. Most studies focused on vertebrates, revealing that individual cognitive performance can be stable across time and tasks and linked to other behavioural trait...
